agricultural science and farm technology and by reason of it a tenure holder can overcome hurdles and raise two crops in a year over the entire extent of a land having irrigation facility. We need not go as far as that. The normal presumption, in the absence of contra-material, would be that the quality and content of soil of a land would be uniform throughout its extent. Such being the case, if a tenure holder is able to raise two crops in a year in a portion of the land, then it would be logical to hold that the other portions of the land also would have the capacity to yield two crops if the tenure holder had utilised the entire extent to raise two crops instead of utilising a portion of the land alone. The raising of two crops even on a portion of the land will prove, in the absence of material to show poor quality of soil in portions of the land due to salinity etc., the uniform nature and content of the soil of the entire land. The High Court was therefore right in holding that the Prescribed Authority can treat a land, having assured irrigation facility, as 'irrigated land' if the tenure holder had raised two crops even m a portion of the land during anyone of the prescribed years and that it is not necessary that the raising of the two crops should have been made on the entire extent of the land in order to classify the land as 'irrigated land'.
